Multiple Sclerosis
Multiple Sclerosis
Multiple Sclerosis Multiple Sclerosis is a disease that bewilders us all.. There is no known cause. We do know that MS (multiple sclerosis) is a disease where the myelin breaks down and is replaced by scar tissue. The demyelination can slow down or block the flow of signals to and from the central nervous system to the rest of the body, impairing such functions as vision, strength, and coordination.1 While we do know what MS is we still don't know why, where and when people contract the disease

Brazil: National Context Geography Brazil occupies almost one-half of the entire South America continent, and is the fifth largest country in the world. It borders all Latin American countries except Chile and Ecuador. The 9,170km coastline and the 50,000km navigable inland waterways provide great potentials for water transportation which has not been well developed. Brazil is topographically relatively flat. 40% of the land is under the Amazon Rain Forest. Most of the arable land is found in th

Madagascar: The Exotic Island
Madagascar: The Exotic Island Looking at a map of the southern hemisphere, one wouldn't expect such a seemingly small island to be so exotic and bountiful, but the island of Madagascar is just that. A 226,658 square mile (587,041 square kilometers) piece of land, with a a coastline of about 2,480 miles (3,990 kilometers), it's a beautiful and different view of its large neighbor, Africa. The island itself is made up of ridges, rivers, valleys, and tropical forests sectioning off the different
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides oz

The Rain Forest
The Rain Forest The destruction of the rainforest is a problem that the people of the world can not continue to ignore. 14 percent of the Earth's land used to be covered by rainforests yet this number has dropped significantly to only about 6 percent (http://www.ran.org/ran/info_center/index.html). Rainforests provide the people of the world with many necessities, some of which would no longer be available if rainforests did not exist. In the last 50 years, rainforests have declined at a terrify

Manatees
Manatees Quietly, but swiftly, the plump, dark animal glided across the water while making sounds comparable to that of the squeaks and squeals of a whale (Florida Manatee 1). Some would say these aquatic mammals are the ugliest thing below the surface, others would say that these animals are beautiful and resemble portly mermaids, but no matter what anybody says about the manatees, they are unique creatures (Ray and Ciampi 315). They are mammals that are completely harmless, they feed mostly

History of the Problem Some scientist's have been concerned since 1896 about what might happen if there were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a British scientist did an experiment showing that the carbon in the air was absorbing some of the sun's radiation. Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would in

Human Evolution Human Evolution, the biological and cultural development of the species Homo sapiens, or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa, Europe, and Asia. Tools of stone, bone, and wood, as well as fire hearths, campsites, and burials, also have been discovered and excavated. As a result of these discoveries, a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are c
Effects Of Deforestation
Effects Of Deforestation
Effects of Deforestation The subject of deforestation and the effects that it has on the environment have been heavily debated for a long time; particularly over the last few years. Governments and large lumber companies see large profits in the mass deforestation of forests and state that their actions are having few, if any, harmful effects on the environment. Most people disagree with this and think that the environmental effects are devastating and will become irreversibly disastrous in the

Acid Rain
Acid Rain
Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries, coal burning factories, power plants and automoble engines are the

Plants
Plants What makes plants grow? Several people have puzzled over this question. There is no one single answer to this. Several factors contribute: Tropisms, environment, hormones, biological clocks, and even humans. We are trying to determine the effects of music on plants. It takes all these combined to have a plant that actually grows and a plant that is healthy and happy in its habitat. Hormones Hormones contribute greatly to the growth of plants. Hormones such as auxins, gibberellins, cytoki

The Enviromnetal Degradation as a Result of Overpopulation 1 Introduction There are simply too many people on our planet, and the population is not showing any signs of slowing down(see Figure 1). It is having disastrous effects on our environment. There are too many implications and interrelationships to discuss in this paper, but the three substances that our earth consists of: land, water and air, are being destroyed. Our forests are being cut down at an alarming rate, bearing enormous impact

The History Of Dinosaurs
The History of Dinosaurs The dinosaurs were reptiles that appeared about 230 million years ago. It's believed that they had scaly skin and some ate plants and others ate meat. Scientists don't know whether or not the dinosaurs were cold blooded, but they think the smaller ones were warm blooded, and the large ones were cold-blooded. In this report you'll learn about the earliest dinosaurs, the kinds of dinosaurs, and how the dinosaurs died. There are two main groups of the earliest dinosaurs: T

Temperate Rainforest Many temperate rain forests have summer fogs that keep the forests cool and moist in the hottest months. Coastal mountains: temperate rain forests occur where mountain ranges are close to the coast; coastal mountains increase rainfall on the ocean-facing slopes. The average annual rainfall in the Temperate Rainforests of the Pacific Northwest is 145 in.(Cavendish). Temperate Rainforests around the world average from 60-200 inches of rainfall per year.

Bioinformatics Introduction When the Human Genome Project was begun in 1990 it was understood that to meet the project\'s goals, the speed of DNA sequencing would have to increase and the cost would have to come down. Over the life of the project virtually every aspect of DNA sequencing was improved. It took the project approximately four years to sequence its first one billion bases but just four months to sequence the second billion bases. During the month of January, 2003, 1.5 billion bases
